1-(2,6-dinitro-phenyl)-pyridinium chloride is a chemical compound with the molecular formula C11H6ClN3O4. It is a derivative of pyridinium, a heterocyclic compound with a nitrogen atom in the ring structure. The compound features a 2,6-dinitro-phenyl group attached to the pyridinium ring, which imparts a strong electron-withdrawing effect due to the presence of two nitro groups. This results in a highly reactive and polar molecule. The chloride ion is associated with the positively charged pyridinium ring, forming an ionic bond. 1-(2,6-dinitro-phenyl)-pyridinium; chloride is often used in chemical research and as an intermediate in the synthesis of various organic compounds. It is important to handle this substance with care due to its potential reactivity and the presence of nitro groups, which can be hazardous under certain conditions.
The CAS Registry Mumber 6526-53-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,2 and 6 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 6526-53: (6*6)+(5*5)+(4*2)+(3*6)+(2*5)+(1*3)=100 100 % 10 = 0 So 6526-53-0 is a valid CAS Registry Number.
